Codex x ElevenLabs Buildathon - Ho Chi Minh City
Build More. Spend Less. Ship Faster. 🚀
We collaborate with ElevenLabs, BuildStuffs community and sixonefourlabs school to bring a build-together session.
OpenAI just made frontier AI dramatically more affordable. GPT‑5.6 Luna is now 80% cheaper, Terra is 20% cheaper, and Sol Fast can run up to 2.5× faster.
What does that unlock for Vietnamese developers, founders, and startups?
Join the OpenAI Codex Vietnam community in Ho Chi Minh City for a practical evening exploring how to build more with the same budget. We’ll break down when to use Luna, Terra, and Sol—and demonstrate how Codex can take an idea from prompt to working product.
Expect:
A clear guide to the new GPT‑5.6 pricing and model choices
Live Codex demos and practical startup workflows
Ideas for reducing AI costs without sacrificing quality
Community sharing, networking, and conversations with local builders
Whether you’re building your first AI project or scaling a production application, you’ll leave with workflows you can use immediately.

The live build should explicitly demonstrate model choice:
Sol for planning and difficult judgment.
Terra for normal implementation.
